style="text-indent:25px">變薄拉伸加工：與普通拉伸不同，變薄拉伸主要是在拉伸過程中改變拉伸件筒壁的厚度。凸凹模之間的間隙小于毛坯厚度，毛坯直壁部分在通過間隙時，處于較大的均勻壓應(yīng)力之下，拉伸過程中壁厚變薄的同時，消除容器壁厚偏差，增加容器表面的光滑度，提高精度和強度。面板拉伸加工：面板產(chǎn)品是板材沖壓件，表面形狀復(fù)雜。在拉伸工序中，毛坯變形復(fù)雜，其成形性質(zhì)已非簡單的拉伸成形，而是拉深與脹形同時存在的復(fù)合成形。逆向拉伸加工：將前工序的拉伸工件進(jìn)行反向拉伸，工件內(nèi)側(cè)變成外側(cè)，并使其外徑變小的加工。不銹鋼拉伸中導(dǎo)致開裂形成的原因有。福田防腐精密拉伸五金件模具</p><p

1、拉伸加工：使用壓板裝置，利用凸模的沖壓力，將平板材的一部分或者全部拉入凹模型腔內(nèi)，使之成形為帶底的容器。容器的側(cè)壁與拉伸方向平行的加工，是單純的拉伸加工，而對圓錐(或角錐)形容器、半球形容器及拋物線面容器等的拉伸加工，其中還包含擴(kuò)形加工。 </p> <p> <br /> </p> <p> 2、再拉伸加工：即對一次拉伸加工無法完成的深拉伸產(chǎn)品，需要將拉伸加工的成形產(chǎn)品進(jìn)行再次拉伸，以增加成形容器的深度。 </p> <p> <br /> </p> <p> <br /> 福田防腐精密拉伸五金件模具</p><p
